Manifestations Of An Acute Episode
Acute episodes can be mild, moderately severe, severe, or characterized by imminent respiratory arrest.
Mild episodes
During a mild episode, patients may be breathless after physical activity such as walking they can talk in sentences and lie down and they may be agitated. Patients with mild acute asthma are able to lie flat. In a mild episode, the respiratory rate is increased, and accessory muscles of respiration are not used. The heart rate is less than 100 bpm, and pulsus paradoxus is not present. Auscultation of the chest reveals moderate wheezing, which is often end expiratory. Rapid forced expiration may elicit wheezing that is otherwise inaudible, and oxyhemoglobin saturation with room air is greater than 95%.
Moderately severe episodes
In a moderately severe episode, the respiratory rate also is increased. Typically, accessory muscles of respiration are used. In children, also look for supraclavicular and intercostal retractions and nasal flaring, as well as abdominal breathing. The heart rate is 100-120 bpm. Loud expiratory wheezing can be heard, and pulsus paradoxus may be present . Oxyhemoglobin saturation with room air is 91-95%. Patients experiencing a moderately severe episode are breathless while talking, and infants have feeding difficulties and a softer, shorter cry. In more severe cases, the patient assumes a sitting position.

Medical Treatments For Children With Noisy Breathing
Treatment for noisy breathing depends on the underlying cause. A child who is sick and wheezing, for example, may be less concerning than a child who has wheezing that stems from both lungs without any noticeable illness.
Successful treatment often hinges on having a team of professionals, including an ear, nose, and throat specialist a pulmonologist a gastroenterologist and sometimes a cardiologist. Doctors may take a “wait-and-see approach,” while providing children with supportive care such as a nebulizer to help them breathe easier. Other cases call for immediate surgery.
“If your child is struggling to breathe or showing signs of labored breathing, such as bluish hue on the lips, skin or body or the chest collapsing inward, call 9-1-1 or take your child to the nearest emergency room,” notes Walsh.
Questions your doctor will ask that will inform your child’s treatment:
- When did you first notice the condition?
- Has your child been ill recently?
- Did your child put a foreign object in his mouth?
- Does your child have trouble swallowing?
- Is your child struggling to breathe?
Lung Volumes Depend On The Age Sex Ethnicity And Built
The lung capacities and volumes tend to increase as the size of the body increases and are higher in males compared to females. As the age increases after the third decade, the residual volume and the functional residual capacity increases due to the stiffening of the lungs as the elastic recoil forces tend to decrease with ageing. The tidal volume and the expiratory reserve volume decreases but the total lung capacity remains relatively constant.

How Is Wheezing Treated
Your treatment for wheezing depends on its underlying cause. If wheezing is severe or interfering with breathing, you may need to be hospitalized until your breathing improves.
Asthma. If your wheezing is caused by asthma, youll likely be prescribed a type of inhaler to reduce inflammation and open your airways . Inhaled corticosteroids and pills such as montelukast are anti-inflammatory medicines used to treat asthma.
Bronchitis. If your doctor determines bronchitis is causing your wheezing, you may be prescribed a bronchodilator such as albuterol or an antibiotic to heal a bacterial infection. This should help you breathe better as you recover.
Other causes of wheezing may require specific treatments. Your doctor will prescribe a plan to treat the underlying cause of your condition, as well as soothe symptoms to help you feel better faster.
How To Stop Wheezing
The best way to deal with wheezing is to treat the underlying condition that’s causing it.
For asthma or COPD, your doctor will likely prescribe an inhaler or other medications that help keep your airways relaxed and free of phlegm and other obstructions. For the more rare causes of wheezing, like the presence of a lodged piece of food or vocal cord dysfunction, more advanced treatments are needed.
And when it comes to the mild wheezing that sometimes accompanies a cold, the flu or COVID-19, the sensation may come and go for the duration of your illness, unfortunately. To expedite your recovery, be sure to get plenty of rest and take any medications you doctor may have prescribed.
In the meantime, you can also try one of the following home remedies for wheezing:
- Drinking warm fluids
- Breathing moist air by taking a steamy shower or using a humidifier
- Avoiding smoking or being exposed to smoke
- Avoiding cold, dry air

General Manifestations Of Asthma
Wheezing, a musical, high-pitched, whistling sound produced by airflow turbulence, is one of the most common symptoms. In the mildest form, wheezing is only end expiratory. As severity increases, the wheeze lasts throughout expiration. In a more severe asthmatic episode, wheezing is also present during inspiration. During a most severe episode, wheezing may be absent because of the severe limitation of airflow associated with airway narrowing and respiratory muscle fatigue.
Asthma can occur without wheezing when obstruction involves predominantly the small airways. Thus, wheezing is not necessary for the diagnosis of asthma. Furthermore, wheezing can be associated with other causes of airway obstruction, such as cystic fibrosis and heart failure. Patients with vocal cord dysfunction, now referred to as inducible laryngeal obstruction , have a predominantly inspiratory monophonic wheeze , which is heard best over the laryngeal area in the neck. Patients with excessive dynamic airway collapse , bronchomalacia, or tracheomalacia also have an expiratory monophonic wheeze heard over the large airways. In exercise-induced bronchoconstriction, wheezing may be present after exercise, and in nocturnal asthma, wheezing is present during the night.
Do Lung Volumes Tell Us Anything Meaningful About Obstruction
Residual volume upper limit of normal plotted as a percentage of the predicted value. Height and age of white subjects enrolled in the National Health and Nutrition Examination Survey III study were used to calculate the predicted RV and its upper limit of normal, using the European Community for Coal and Steel equations. All values fall above 120% of predicted, a value frequently used as the upper limit of normal when assessing air-trapping.
Dykstra and colleagues evaluated TLC, RV, and the RV/TLC ratio in a large group of patients with airway obstruction to see whether lung volumes could discriminate between asthma and COPD. They found that RV and RV/TLC were more sensitive than TLC to the degree of airway obstruction. As airway obstruction falls from mild to moderate , RV increases while TLC tends to remain the same. In general, lung volumes are not able to distinguish whether the increases are caused by COPD versus asthma, particularly when the diseases have progressed to moderate or severe airway obstruction. However, as shown in , there is a great deal of variability in RV/TLC, particularly around the LLN for FEV1. Although RV or RV/TLC may not help make a diagnosis as to whether the patient has asthma or COPD, it may be important to know how much hyperinflation is present if reducing it is a therapeutic goal.,

When Should I Worry About Wheezing
With a bodily process as essential as breathing, it’s certainly concerning when you notice a change even if it’s just a slight difference in how it sounds, like a wheeze.
If you’re wheezing when breathing out, it’s a sign that air in your airway isn’t flowing as optimally as it usually does, likely because the airway is narrowed or partially blocked.
“Wheezing isn’t always a significant cause for concern, but it can indicate an underlying health issue in some cases a few of which are very serious so it’s important to know when wheezing needs to be evaluated,” says Dr. Rodney Folz, a pulmonologist at Houston Methodist.

Inspiratory Vs Expiratory Wheezing
There are two main types of wheezing inspiratory and expiratory .
Its easier to hear expiratory wheezing because your airways narrow more during this breathing phase. Sometimes, expiratory wheezing is loud enough to hear on its own. Expiratory wheezing alone often indicates a mild airway obstruction.
Inspiratory wheezing occurs when you inhale. In some people with asthma, you can only hear wheezing during the inspiratory phase.
If youre wheezing when you exhale and inhale, you could have a more severe breathing issue. To diagnose what type of wheezing you have, your doctor will use a stethoscope to hear if its loudest over your lungs or neck.
Inspiratory wheezing often accompanies expiratory wheezing when heard over the lungs, specifically in acute asthma. However, if inspiratory wheezing or stridor is heard over the neck, that could be an indication of a serious upper airway obstruction.
What Would A Larger Vital Capacity Indicate
Vital capacity is the maximum amount of air a person can expel from the lungs after a maximum inhalation. A persons vital capacity can be measured by a wet or regular spirometer. In combination with other physiological measurements, the vital capacity can help make a diagnosis of underlying lung disease.

Why Do My Lungs Wheeze When I Lay Down
Wheezing while lying down is a common symptom of conditions such as asthma. It can also be the result of anxiety at night, GERD, or obesity. Some people may have a combination of several conditions. For example, those with GERD and asthma may find that acid reflux triggers their asthma symptoms when lying down.
Signs You Actually Have Severe Asthma
Breathing is just one of those things you take for granted until it feels like every inhale or exhale is a struggle. Unfortunately, people with severe asthma have to deal with breathing issues way more often than anyone should, and it can be completely terrifying.
Asthma is a respiratory condition that affects the airways that extend from your nose and mouth to your lungs, according to the National Heart, Lung, and Blood Institute . When youre exposed to triggers like animal fur, pollen, mold, exercise, and respiratory infections, these airways can narrow, restricting your airflow. This can then make the muscles surrounding your airways constrict, making it even harder to breathe, and cause your airways to produce more mucus than normal, further compounding the problem. All together, this can lead to asthma symptoms like shortness of breath, coughing, wheezing , and chest tightness or pain, according to the NHLBI.
Like most health conditions, asthma severity runs along a spectrum, Emily Pennington, M.D., a pulmonologist at the Cleveland Clinic, tells SELF. Some people have cases where they experience minor symptoms here and there . Others can have asthma that is basically an ever-present problem and might result in scary asthma attacks, which is when symptoms ramp up in severity and can even become life-threatening.

Is It Possible To Increase Vital Capacity
Another way to increase lung capacity is to improve exercise tolerance. Exercise causes your heart and breathing rates to increase, so your body has enough oxygen and strengthens your heart and lungs. The average persons lung capacity can be improved around 5 percent to 15 percent even with frequent workouts.
Peak Expiratory Flow Rate
PEFR monitoring is a simple and costeffective means of determining the degree of airways obstruction. PEFR is a tool for monitoring patients with asthma, but it should not be used for the diagnosis of asthma. Patients with moderate or severe asthma should be instructed in the use of PEFR and have a peak flow meter accessible for selfmonitoring.
Patients should establish a baseline personal best PEFR. At a time when asthma symptoms are wellcontrolled, readings should be obtained at least twice daily over a 2 to 3week period, with one reading when the patient wakes up and another between noon and 2:00 pm. Readings should also be obtained pre and postbeta2 agonist use.
PEFR zones are defined by the EPR2 as follows:
-
Green Zone: > 80% of personal best peak flow. These readings represent good asthma control, and patients should continue taking their medications without change.
-
Yellow Zone: > 50%, but < 80% of personal best peak flow. Patients with readings in this range should exercise caution. A short-acting inhaled beta2 agonist should be taken immediately, and the patient should contact the physician regarding any potential changes to the asthma regimen.
-
Red Zone: < 50% of personal best peak flow. Patients should be on the alert, take their short-acting inhaled beta2 agonist, and contact their physician or the emergency department immediately. Patients may also go to their nearest emergency room.

How Does Lung Volume Control Inspiration
During inspiration, the diaphragm contracts and pulls downward while the muscles between the ribs contract and pull upward. During expiration, the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases. As a result, the lungs contract and air is forced out.
You may ask, Why do alveoli collapse?
Without normal surfactant, the tissue surrounding the air sacs in the lungs sticks together after exhalation, causing the alveoli to collapse.
Treating Inspiratory And Expiratory Wheezing
Treating wheezing ultimately depends on the underlying cause. If your wheezing is severe, your doctors may give you an oxygen mask to steady your breathing and bronchodilators to help open your airways. In this case, they may recommend you stay at the hospital overnight.
If inflammation is causing your wheezing, your doctor will prescribe anti-inflammatory medications like steroids to reduce swelling and open your airways for easier breathing.
If your wheezing is caused by an infection, you may be prescribed antibiotics to treat the condition and associated symptoms.
If youre diagnosed with asthma, your doctor will prescribe you medication, usually an inhaler.

Lung Volumes And Lung Capacities In Health And Respiratory Diseases
The changes in the volumes of the lungs occur in a predictable manner during quiet breathing and deep breathing. Four such measurable volumes have been described and based on the four volumes four capacities have been defined.
Tidal volume volume inhaled or exhaled during quiet breathing
Inspiratory Reserve Volume volume inhaled in excess of the TV in a deep inspiration
Expiratory Reserve Volume volume exhaled in excess of the TV and IRV in a deep expiration
Residual Volume volume that remains in the respiratory tract following a deep expiration
Inspiratory Capacity = TV + IRV
Vital Capacity = IRV + TV + ERV
Functional Residual Capacity = ERV + RV
Total Lung Capacity = IRV + TV + ERV + RV

What Is Worse Inspiratory Or Expiratory Wheezing
Wheezing during expiration alone indicates milder obstruction than wheezing during both inspiration and expiration, which suggests more severe airway narrowing. By contrast, turbulent flow of air through a narrowed segment of the large, extrathoracic airways produces a whistling inspiratory noise (stridor.

Alcohol Effects On Lungs
Heavy alcohol use can cause damage to the lungs in a few different ways. It can interfere with the immune system that keeps the lungs healthy and able to fight off infections. It can also harm the surface cells that line the insides of the lungs.
Every day, a person inhales things in the air from which the lungs and immune system try to protect them. Parts of the lungs are even lined with moving, hair-like cells called cilia whose job it is to sweep things inhaled out of the lungs. Heavy alcohol> use harms this whole process.
Alcohols damage to lung cells and the immune system is so well known that it is a syndrome termed alcoholic lung. One study showed that chronic alcohol use can start to harm the lungs in as little as six weeks.
Alcohol abuse can also cause inflammation and harm cells in both the upper and lower parts of the airway. Its not the alcohol in its liquid form that does this, it is actually the vapor. Alcohol, after all, is an irritating chemical.
After a person drinks alcohol, besides going into the bloodstream, some of it will diffuse out into the lungs and end up in the breath. Breathalyzer tests work because the alcohol is partly breathed out in vapor form. But when it is in vapor form, then it is free to cause damage to the airway. This damage happens not only in the lungs but also in the nasal passages and sinuses, causing inflammation and making them less able to fight off infection.
